What’s on your bucket list? African safari? Skydiving? How about running 100 miles at 12,000 feet above sea level? If you’re that, uh, crazy, we’ve got the to-do list for you: Colorado Springs–based Chris Carmichael, an Olympic coach and founder of Carmichael Training Systems (CTS), has rolled out the Epic Endurance Bucket List, a yearly series of hand-picked running, cycling, and triathlon races that challenge the world’s fittest athletes. “These events are too hard to be taken lightly,” Carmichael says. “All athletes reach a point, at least once, when they are on the brink of failing. We achieve satisfaction and exhilaration from pushing ourselves—body and mind—as far as we can.” The list will change each year and includes training programs, logistical support, and even simulation camps for some races. Go ahead: Train like the pros.
